Modified NASA keybindings

Mappings still in progress
*NOTE*: These are the chords I use. The code of the spiffchorder can be easily modified allowing you to set the chords any way you like. This just happens to be what I am use to. -Greg

A few general notes

As a general rule the spiffchorder is using the standard keybindings were possible. This is a benifit as most of you are coming to chording already familiar with the QWERTY keyboard. As such prefixing a chord with <key>Shift</key> does what you would expect, <key>Shift - ] </key> generates <key> } </key>, <key>Shift - 3</key> generates <key>#</key> and so on.

There are lots of chord possibilities, if you look at the nasa_us.h file you will see quite a few empty spaces associated with posible chords. At the same time, this welth of chords offers the oportunity for several chords to generate the same key. For example, there are at least 2 ways to get a Question Mark <key>?</key>, you don't need to learn both, just the one that works for you.1)

There are a number of ways to think about the chords, usually one will make the most sence to you. Here are two ways to chart them out.

Motion, Editing and Mouse Emulation on The Far Thumb

The outer thumb button,Far in addition to functioning as the shift key has cursor movement chords on it. Pressing Far and Center together generates the key codes from the numeric keypad in place of the ones from the keyboard cursor and movement keys.

Microsoft Windows and X11R6 (a windowing system used in Linux, BSD Unix, Solaris and other flavors of Unix) both allow the numeric keypad to act as a mouse. This setting is usually found in your systems accessibility settings or control panel. By selecting mouse accessibility the spiffcorder can emulate a mouse in the same crude way a numeric keypad can.

Rather than duplicate the entire chart with the only change being the addition of the Center button, the column labled “Change Thumb to <key>C</key><key>F</key>” indicates the keypad codes sent by the chorder when the the chord is made with the thumb pressing <key>C</key><key>F</key> in place of only pressing <key>F</key>. The last column lists the mouse movement or mouse first button action that will be taken if you have set mouse emulation on your computer.9)
